不同材质共享缆绳对浮式风电场系泊响应的影响

Effects of shared lines with different materials on mooring response of the floating wind farm

[目的]旨在合理设计浮式风电场的共享系泊系统,探究不同材质共享缆绳对浮式风电场动力响应的影响。[方法]首先,对浮式风电场设计共享系泊和传统(无共享缆绳)系泊方案,比较两种系泊方案的动力响应和经济成本,验证设计方案的可行性。其次,探究两类共享系泊系统对浮式风电场系泊响应的影响。最后,分析环境载荷的施加方向和缆绳材质对共享缆绳平均张力的影响。[结果]采用不同材质共享系泊系统的浮式风电场,其叶片张力近乎相同;两类共享系泊系统对风机位移和系缆平均张力的影响存在差别。此外,环境载荷施加角度和系缆材质也对风机位移和共享缆绳受力产生影响。[结论]该研究可为系泊系统中共享缆绳选型提供参考。

[Objectives]This paper investigates the impact of shared lines with different materials on the dynamic response of floating wind farms in order to design a rational shared mooring system.[Methods]First,shared mooring and traditional(without shared cables)mooring systems are designed for floating wind farms.The dynamic response and economic cost of the two mooring systems are then compared to validate the feasibility of the shared mooring system design.Second,the influence of the two types of shared mooring systems on the mooring response of floating wind farms is studied.Finally,an analysis is made of the influence of load direction and line material on the tension of the shared lines.[Results]The results indicate that floating wind farms with shared mooring systems using different materials have nearly identical blade tension.However,there are differences in the impact of the two types of shared mooring systems on wind turbine displacement and the mean tension of mooring lines.In addition,the environmental load direction and line material affect wind turbine displacement and shared line tension.[Conclusions]This study provides useful references for selecting material for shared lines in the mooring systems of floating wind farms.
